In 2026, we kick off the public phase of our new venture — the Jay and Carolyn Henges Wetlands Education and Conservation Center — a world-class destination for wildlife habitat, outdoor education, and community engagement. Through partnerships with the Missouri Department of Conservation, the Nature Conservancy, Missouri Conservation Heritage Foundation, and many veteran and first responder groups, this vision is off to a great start. This vision will only be realized through your generosity. We need your help to complete the acquisition and ensure this property serves wildlife and the community FOREVER!
By giving to this campaign, you help ensure that people of all ages and abilities can connect with the hunting heritage and wildlife of the Confluence. Your support fuels habitat restoration, youth mentorship, and refuge for millions of migratory birds and threatened species.
